Question : Problem: **Urgent ** Configure Cisco 1720 Router with a T1

I have a new T1 line and a new Cisco 1720 Router. I have spent 6 hours trying to get this thing working and I know that I am missing something stupid.

If I spell out the scenario, and all of it's details, can someone provide me the necessary script??

Here goes:

T1 provider gave me the following:

PVC 1 (Data PVC)
Router's Public IP Address: xxx.xxx.252.158
Router's Public Subnet mask: 255.255.255.0
Router's Default Gateway: xxx.xxx.252.1
Usable Public IP Address Range: xxx.xxx.251.217 - xxx.xxx.251.222
Usable Public IP Address Range subnet mask:  255.255.255.248
Router's Private IP address: xxx.xxx.251.217
Router's Private subnet mask: 255.255.255.248
Usable Private IP Address Range xxx.xxx.251.218 - xxx.xxx.251.222
Router DCLI: 16
Primary DNS Server:  xxx.xxx.0.10
Secondary DNS Server: xxx.xxx.215.254

My network is currently set up as follows:

Server 1 is a dedicated Microsoft ISA server that is completely configured as the firewall and handles all traffic already. It's IP is xxx.xxx.1.1

For now, all I want to happen is for the T1 to hit my cisco router and be sent straight through to the ISA server.

Thanks in advance for the help.

Answer : Problem: **Urgent ** Configure Cisco 1720 Router with a T1

Do the indicators change if you turn off the keepalives?
Do you ger Serial 0 up line protocol up?
Does DLCI=16 change status to ACTIVE?

Sounds like a call to the telco provider....
